QUESTION NO: 1
A company has an on-premises Microsoft SQL Server environment and Microsoft Azure SQL
Database instances. The environments host several customer databases.
You configure an Always On Availability Group for a customer. You must create log reports for the customer that detail when the log is flushed to disk on the primary and secondary replica.
You need to develop a report containing the requested information.
In the table below, identify the log type that you should use for each replica.
NOTE: Make only one selection in each column. Each correct selection is worth one point.
Answer:
Explanation
Flush on primary: Log flush
Log flush. Log data is generated and flushed to disk on the primary replica in preparation for replication to the secondary replica. It then enters the send queue.
Flush on secondary: Log hardened
The log is flushed on the secondary replica, and then a notification is sent to the primary replica to acknowledge completion of the transaction.

QUESTION NO: 2
General Overview
You are the Senior Database Administrator (DBA) for a software development company named
Leafield Solutions. The company develops software applications custom designed to meet customer requirements.
Requirements Leafield Solutions has been asked by a customer to develop a web-based Enterprise
Resource Planning and Management application. The new application will eventually replace a desktop application that the customer is currently using. The current application will remain in use while the users are trained to use the new webbased application.
You need to design the SQL Server and database infrastructure for the web-based application.
Databases
You plan to implement databases named Customers, Sales, Products, Current_Inventory, and
TempReporting.
The Sales database contains a table named OrderTotals and a table named SalesInfo.
A stored procedure named SPUpdateSalesInfo reads data in the OrderTotals table and modifies data in the SalesInfo table.
The stored procedure then reads data in the OrderTotals table a second time and makes further changes to the information in the SalesInfo table.
The Current_Inventory database contains a large table named Inv_Current. The Inv_Current table has a clustered index for the primary key and a nonclustered index. The primary key column uses the identity property.
The data in the Inv_Current table is over 120GB in size. The tables in the Current_Inventory database are accessed by multiple queries in the Sales database.
Another table in the Current_Inventory database contains a self-join with an unlimited number of hierarchies.
This table is modified by a stored procedure named SPUpdate2.
An external application named ExternalApp1 will periodically query the Current_Inventory database to generate statistical information. The TempReporting database contains a single table named
GenInfo.
A stored procedure named SPUPdateGenInfo combines data from multiple databases and generates millions of rows of data in the GenInfo table.
The GenInfo table is used for reports.
When the information in GenInfo is generated, a reporting process reads data from the Inv_Current table and queries information in the GenInfo table based on that data.
The GenInfo table is deleted after the reporting process completes. The Products database contains tables named ProductNames and ProductTypes.
Current System
The current desktop application uses data stored in a SQL Server 2005 database named
DesABCopAppDB.
This database will remain online and data from the Current_Inventory database will be copied to it as soon as data is changed in the Current_Inventory database.
SQL Servers
A new SQL Server 2012 instance will be deployed to host the databases for the new system. The databases will be hosted on a Storage Area Network (SAN) that provides highly available storage.
Design Requirements
Your SQL Server infrastructure and database design must meet the following requirements:
* Confidential information in the Current_ Inventory database that is accessed by ExternalApp1 must be securely stored.
* Direct access to database tables by developers or applications must be denied.
* The account used to generate reports must have restrictions on the hours when it is allowed to make a connection.
* Deadlocks must be analyzed with the use of Deadlock Graphs.
* In the event of a SQL Server failure, the databases must remain available.
* Software licensing and database storage costs must be minimized.
* Development effort must be minimized.
* The Tempdb databases must be monitored for insufficient free space.
* Failed authentication requests must be logged.
* Every time a new row is added to the ProductTypes table in the Products database, a user defined function that validates the row must be called before the row is added to the table.
* When SPUpdateSalesInfo queries data in the OrderTotals table the first time, the same rows must be returned along with any newly added rows when SPUpdateSalesInfo queries data in the
OrderTotals table the second time.
The performance of the SPUpdate2 stored procedure needs to be improved.
Your solution must meet the design requirements.
What should your solution include?
A. A table variable.
B. A common table expression.
C. A Cursor.
D. A derived table.
Answer: B

QUESTION NO: 3
Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
You are a database administrator for a company that has an on-premises Microsoft SQL Server environment and Microsoft Azure SQL Database instances. The environment hosts several customer databases, and each customer uses a dedicated instance. The environments that you manage are shown in the following table.
You need to configure auditing for WDWDB.
In the table below, identify the event type that you must audit for each activity.
Answer:
Explanation

QUESTION NO: 4
Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
Start of repeated scenario.
You have five servers that run Microsoft Windows 2012 R2. Each server hosts a Microsoft SQL Server instance. The topology for the environment is shown in the following diagram.
You have an Always On Availability group named AG1. The details for AG1 are shown in the following table.
Instance1 experiences heavy read-write traffic. The instance hosts a database named
OperationsMain that is four terabytes (TB) in size. The database has multiple data files and filegroups.
One of the filegroups is read_only and is half of the total database size.
Instance4 and Instance5 are not part of AG1. Instance4 is engaged in heavy read-write I/O.
Instance5 hosts a database named StagedExternal. A nightly BULK INSERT process loads data into an empty table that has a rowstore clustered index and two nonclustered rowstore indexes.
You must minimize the growth of the StagedExternal database log file during the BULK INSERT operations and perform point-in-time recovery after the BULK INSERT transaction. Changes made must not interrupt the log backup chain.
You plan to add a new instance named Instance6 to a datacenter that is geographically distant from
Site1 and Site2. You must minimize latency between the nodes in AG1.
All databases use the full recovery model. All backups are written to the network location
\\SQLBackup\. A separate process copies backups to an offsite location. You should minimize both the time required to restore the databases and the space required to store backups. The recovery point objective (RPO) for each instance is shown in the following table.
Full backups of OperationsMain take longer than six hours to complete. All SQL Server backups use the keyword COMPRESSION.
You plan to deploy the following solutions to the environment. The solutions will access a database named DB1 that is part of AG1.
* Reporting system: This solution accesses data inDB1with a login that is mapped to a database user that is a member of the db_datareader role. The user has EXECUTE permissions on the database.
Queries make no changes to the data. The queries must be load balanced over variable read-only replicas.
* Operations system: This solution accesses data inDB1with a login that is mapped to a database user that is a member of the db_datareader and db_datawriter roles. The user has EXECUTE permissions on the database. Queries from the operations system will perform both DDL and DML operations.
The wait statistics monitoring requirements for the instances are described in the following table.
End of repeated scenario.
You need to reduce the amount of time it takes to back up OperationsMain.
What should you do?
A. Run the following Transact-SQL statement for each file in OperationsMain: BACKUP DATABASE
OperationsMain FILE [...]
B. Modify the backup script to use the keywords INIT and SKIP in the WITH statement.
C. Run the following Transact-SQL statement: BACKUP DATABASE OperationsMain
READ_WRITE_FILEGROUPS
D. Modify the backup script to use the keyword NO_COMPRESSION in the WITH statement.
Answer: C
Explanation
READ_WRITE_FILEGROUPS specifies that all read/write filegroups be backed up in the partial backup.
If the database is read-only, READ_WRITE_FILEGROUPS includes only the primary filegroup.
Scenario: Full backups of OperationsMain take longer than six hours to complete. All SQL Server backups use the keyword COMPRESSION.

QUESTION NO: 5
Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
Start of repeated scenario.
You are a database administrator for a company that has on-premises Microsoft SQL Server environment.
There are two domains in separate forests. There are no trust relationships between the domains.
The environment hosts several customer databases, and each customer uses a dedicated instance running SQL Server 2016 Standard edition. The customer environments are shown in the following table.
End of repeated scenario.
You need to configure auditing for WDWDB.
In the table below, identify the event type that you must audit for each activity.
NOTE: Make only one selection in each column.
Answer:
Explanation
You must log any deletion of views and all database record update operations.
